Wrenches,
What have you found as good, inexpensive DC-rated (up to 50 or 125V DC--most
are either 250 VDC or 600 VDC anyway, if they're DC-rated at all) unfused
and Class R-fused disconnects for assembling small (cabin-type) PV systems?
Extra big enclosures are worth extra points, to mount shunts, etc.

2-pole unfused:

2-pole fused:

3-pole unfused:

3-pole fused:

We sometimes use circuit breaker load centers (QO2-4/70S or QO6-12/100S)
with a Class R fuse inside for AIC protection, but I'm just looking for
other inexpensive solutions that are OK for DC applications.

Thank you
Allan at Pos E
